ORDER NUMBER DOC2326960
PEM-X1 CG
Prerequisites for perfect grounding and coating of a work piece are:
– clean suspension of the work piece to be coated,
– the grounding resistance of the work piece must not exceed 1 M
(resistance to ground measured at 500 V or 1000 V).
Sparks between conveyor, conveyor hooks (hangers) and work piece can occur
if electric contact points between conveyor, conveyor hooks (hangers) and work
piece are not suciently cleaned and therefore the work pieces are not suciently
grounded! These sparks can cause heavy radio frequency interference (EMC).
